CARA MEMPERBAIKI BATERAI ( CORDLESS ) BOR, GERINDA MATI ketika dipakai

How to repair a drill or grinder battery that dies immediately when used in a machine. This doesn't mean the battery is dead or damaged, but rather the battery's current is cut off by the MOSFET in the BMS system. In this video, I'll show you the solution: how to jumper the battery. I've actually tried this method for a while, and it's been safe and sound. Its performance... When charging, the battery is charged through the BMS. And when used in a machine, the battery supplies its voltage directly through the series battery, without going through the BMS. This battery jumper method can also determine battery quality... If the battery feels powerful after being jumpered and used in a machine, and the machine takes a long time to drain the battery voltage, it's a good battery. This method isn't really a good idea... But rather than having the battery fail, it's better to maximize its function before replacing it with a better cell.
